Various electronics modules are available for mounting options 1 and 2 (integrated or remote electronics). Additionally, there are electronics modules with integrated surface sensing with which front plates can be made touch-sensitive for guard alerts etc. As an alternative to the EF 031 series of front plates, analogue intercom modules can be connected. This allows for custom front plate design. Please note: Electronics modules and flush mount boxes need to be ordered separately.
